Who is that masked man? Fans don't actually know who DSK CHK is, but they still jump up and down to the music of the performance DJ who wears a Guy Fawkes mask. DSK CHK brings his "Fantazia: Cirque Du Rage" show to Pearl Nightclub, 349 East Ave., at 10 p.m. Thursday. Tickets are $12; $20 VIP. For more, go to http://on.fb.me/12nXoPj or www.wantickets.com/LA.
